Answer:

The domain is (-infinity, -3) ∪ (-3, 3) ∪ (3, infinity)

Step-by-step explanation:

This function is defined for all t such that the denominatory t^2 - 9 is not zero (0). Purposely setting t^2 - 9 = 0, we find that t = 3 or t = -3.

This function defined everywhere except at {-3, 3}.

The domain is (-infinity, -3) ∪ (-3, 3) ∪ (3, infinity)

Which equation describes the circle having center point (3,7) and the radius r=4 in Standard form

Annette [7]

The equation of circle in standard form is $(x - 3)^2 + (y - 7)^2 = 16$

<h3><u>Solution:</u></h3>

Given that circle having center point (3,7) and the radius r = 4

To find: equation of circle in standard form

<em><u>The equation of circle is given as:</u></em>

$(x - h)^2 + (y - k)^2 = r^2$

Where center (h,k) and radius r units

Given that center point (h , k) = (3, 7) and radius r = 4 units

Substituting the values in above equation of circle,

$(x - 3)^2 + (y - 7)^2 = 4^2\\\\(x - 3)^2 + (y - 7)^2 = 16$

Thus the equation of circle in standard form is $(x - 3)^2 + (y - 7)^2 = 16$
